ABSTRACT:
Buffers for driving interconnection conductors on programmable logic devices are shared between two types of uses, i.e., to drive static programmable connections to interconnection conductors, and to drive dynamically controllable connections to other interconnection conductors. The dynamically controllable connections are preferably tri-statable. Signals for effectuating the dynamic control are preferably generated on the programmable logic device near the tri-state-type connections. For example, a nearby logic module ("subregion") may provide the dynamic control signal. This reduces the extent of routing for, and consequent delay of, the dynamic control signal.
